I would appreciate English references for the following concepts/algorithms
for 3D geometric modeling.

	Line equations in 3D space
	Area and normal vector of concave polygons
	Equation of a plane
	Interior point algorithms for concave polygons
	Surface area of polyhedrons
	Interior point algorithms for polyhedrons
	Spatial reasoning about 3D objects (Are these polygons perpendicular?)
